What is the difference between the trackball and turntable style view modes?
I'm surprised at the analogy used in the wiki concerning Turntable. This is a turntable for scultping with clay. This lets you rotate around the vertical axis so you can see all sides and judge their proportions accordingly. This is why the mode is called turntable.


(reference, Denise Ferragamo)

Trackball lets you rotate freely around a point in 3D space, this is like picking up the object with your hands and rotating it around until the point of interest is visible.
